Bioelectrical impedance measuring device

Abstract

A bioelectrical impedance measuring device comprises a first electrode unit and a second electrode unit which are nearly rectangular in shape and have electrodes for measuring a bioelectrical impedance on the top surfaces thereof, and a control circuit unit which incorporates an electric control circuit for measuring a bioelectrical impedance and is detachably attached to the first electrode unit and the second electrode unit via connection terminals. Accordingly, a user can disassemble the device into the control circuit unit, the first electrode unit and the second electrode unit and stack these units and can therefore carry around or store the device easily.

1. A bioelectrical impedance measuring device comprising: a first electrode unit and a second electrode unit which are nearly rectangular in shape and have electrodes for measuring a bioelectrical impedance on the top surfaces thereof, a control circuit unit which incorporates an electric control circuit for measuring a bioelectrical impedance and is detachably attached to the first electrode unit and the second electrode unit via connection terminals, and
 an auxiliary unit, wherein one end of the first electrode unit and one end of the second electrode unit are placed on the top surfaces of the ends of the control circuit unit and the other end of the first electrode unit and the other end of the second electrode unit are placed on the top surfaces of the ends of the auxiliary unit, whereby the control circuit unit, the first electrode unit, the second electrode unit and the auxiliary unit are detachably assembled via connection terminals. 
 
   
   
     2. The device of  claim 1 , wherein the first electrode unit and the second electrode unit are formed in a nearly concave shape when viewed from a longer side thereof, and the control circuit unit and the auxiliary unit are formed in a nearly convex shape when viewed from a longer side thereof. 
   
   
     3. The device of  claim 1  or  2 , wherein the control circuit unit and the auxiliary unit incorporate load sensors for measuring a body weight. 
   
   
     4. The device of  claim 1  or  2 , wherein the control circuit unit further incorporates:
 an input unit operable by a user to enter personal data, 
 an arithmetic unit for calculating data related to the body composition of the user based on at least the personal data and a measured bioelectrical impedance, and 
 a display unit for displaying the calculated data related to the body composition. 
 
   
   
     5. The device of  claim 3 , wherein the control circuit unit further comprises:
 an input unit operable by a user to enter personal data, 
 an arithmetic unit for calculating data related to the body composition of the user based on at least the personal data and a measured bioelectrical impedance, and 
 a display unit for displaying the calculated data related to the body composition.
